Curvy shapes and crop marks?

I am new to illustrator and I am trying to design an A4 standard presentation folder with curvy pocket on the bottom right hand corner. It is going to bleed to edge but I don't know where to put my crop marks for a curvy chape??
Please can someone help ?
Thanks!

Crop marks in this case are a little irrelevant as the folder will be cut out using a die due to the non-straight shape. But put them at the edge of the curve and then the edges of the other normal corners - basically at the edge of the final shape. I´m sure the printer will add them where needed. And don´t forget to give them the cutter guide - or to save a bit of money have a look at some previous folders they´ve done and ask them for the cutter guide in Illustrator - they should have it.
